Gilead Sciences will acquire Ouro Medicines for up to $2.18 billion to gain rights to CM336 (OM336), an antibody-based autoimmune disease treatment. Ouro licensed the rights to develop, manufacture, and commercialize CM336 outside of mainland China, Hong Kong, Macau, and Taiwan from China's Keymed Biosciences in 2024. Gilead aims to accelerate the global development of CM336, which they believe could be a best-in-class treatment.

The deal reflects Gilead's strategy to bolster its drug pipeline through acquisitions amid upcoming patent expirations.
